This invention relates to a scale of the overand underweight type and more particularly to a scale of the type having a centrally pivoted weigh beam.

It is an object of the invention to provide a scale which is compact in size and requires a minimum counter space and which is readily viewable from more than one side of the scale.

Another object of the invention is to provide a scale in which the weight indicating mechanism and the counterpoise platter are located in vertical alignment within an upstanding casing.

Another object of the invention is to provide a scale in which the weight indicating mechanism may be transversely shifted to positions at 90 angles with respect to each other.

A. further object ci the invention is to provide scale in which the weight indicating mechanism is contained in a hollow upstanding column l at the top of which is located the counterpoise is located at the top oi a hollow column and is enclosed with a transparent hood through which the counterpoise weight is visible.

These and other objects and advantages of the invention will become more apparent from a consideration of the following disclosure taken in conjunction with the drawings in which:

Figure l is a sectional View through one embodiment of a scale according to the invention;

Figure 2 is a perspective view of a portion of the weight indicating mechanism of the scale;

Figure is a sectional view taken along the lines 3m-fi of Figure l; and

Figure i is a sectional view generally similar to Figure B but having the weight indicating mechanism shifted transversely at a 99 angle with that of Figure 3.

The invention resides in a scale, of vthe type having a centrally pivoted weigh beam and an overand underweight vtype indicating means, which is compact in size and requires a minimum of counter space. These features are accomplished by providing an upstanding casing located above one end of the Weigh beam and contain ing the weight indicating means in vertical alignment with the counterpoise weights receiver. The weight indicating means is located within the upstanding body of the casing, while the counterpoise weights receiver is located at the top of the casing in a manner which renders the weights on the counterpoise receiver readily visible to the viewing public.

The invention further contemplates the provision of a plurality of weight indicating pointers in conjunction with a plurality of charts mounted at opposite sides of the upstanding column. The Weight indicating mechanism is adapted for simple adjustment within the column to a position 90 removed from the original position. In this manner the scale may be adjusted for viewing from four diiierent directions.

In Figure 1 of the drawings a scale of the selected type is illustrated as comprising a base Il! upon which is mounted a fulcrum block l2. A fulcrum bearing i4 is positioned on the block I2 and is adapted to pivotally receive the fulcrum pivot I6 which is attached to the weigh beam I8. The horizontal weigh beam ld supports a commodity platter 26 at one end thereof on the platter support 22 which is adapted to receive the commodity supporting bearing 2t which in turn rests upon the commodity supporting pivot 25. The bar 28 is associated with the platter support 22 and is curved upwardly into the i.-shaped arm 3B which is secured at its end to a check link 32 which in turn is pivotall-y connected to the top 34 of the supporting column L25. This linkage arrangement permits parallel movement of the commodity platter to be maintained.

The supporting column 3d is mounted on the base Il! adjacent one end thereof and extends upwardly at right angles thereto. The counterpoise end of the weigh beam i8 comprises a counterpoise pivot 38 which supports a counterpoise bearing te which is associated with a counterpoise support G2. The support t2 has a vertically positioned rod 4.4. attached thereto and the rod M extends vertically within the column 36 through the top 35. thereof and supports a counter-poise weights receiver 45 thereon. The receiver 46 is located outside and above the scale casing AAll which is substantially L-shaped and relicloses the column 35 with all of the mechanism contained thereon and the weigh beam mechanism supported on the base lil. The casing t3 is preferably ka single piece and is adapted to be readily removed from the scale to expose the mechanism for adjustment and cleaning.

The upstanding column 3e has a icl-shaped bracket 5? removably secured thereto by means of the bolt 52. The bracket 55 fits around the column 36 and has a pair of outwardly extending arms 54 and 56 upon which are positioned a pair of vvbearing Ablocks 53 and ci). rihe bearing blocks are Yadapted to receive the `pivot edge 62. rlhe cylinder (i4 is urged upwardly by means of the metal strap which extends around the periphery of the cylinder and is adjustably secured at one end to the rod M by means of the clamp 68. The other end. of the strap or .ribbon 66 is secured to the lower end oi a load counter-balancing spring 'iii by means of the stirrup 12. The spring is anchored at its upper end to the rectangular top Clt of the column The pivot edge an integral part of a cross piece "ill which is attached to the inner periphery of the cylinder by means of the laterally eX- tending lugs ld and (Fig. 2). A pair of 0ppositely disposed pointers dil and S2 are secured oi the cross 'Nl `and are adapted with a pair of corresponding charts, winch ald is iilustrated in Figure 1.

In order the charts and pointers may be viewed from without, the casing dil is provided with pl i of viewing windows i3d and 83. p^ of opposite windows (not shown) may bef ci. d in the sides oi the casing transverse to the windows eti and li desired, a pair of rer oi ble shutters ii@ and may be pro vided in onor to cover the opposite windows which are not n A removable cap or dome of transparent plastic, glass or otl'ier suitable transparent material rests on the top of the casing it on a sho-1Ll der e cap ccvei` the weights receiver il be p-l cviewing public may see the coun poise weight at all times and from every position. it the same ator. .d further advanfe of this arls that the weight is removed from the working and is not lil-:ely to be containinated with the commodity or to hamper the movements of the operator.

By reinov'ng the bolt from the U-bracket Eil and attaching it to the column at right .i i es to original position illustrated in lure e, it is possible to shift the position of the indicating mechanism to facilitate viewcharts from a different angle. Coriding ao to charts and the load counterbolancing are readily made by removing the casing from about the column ilie weight indications then become Viewable gli other pair of opposite windows on the shutters. teadings may be made ont rear or from the sides, as deter space.

in the operation of the scale illustrated herein the operator will place a counterpoise weight hi on the receiver fili. cap Elfi will be replaced so that the view public may see the weight at all times from any position. The rod lid will be shifted. verticaliy downward and will cause the ccunterpoise end of the weigh beam it to be depressed. A commodity will then be placed on the platter 2t in suiiicient amount to cause the commodity end or" the weigh beam ill to be depressed by an amount suilicient to bring the two ends of the weigh beam into counter-balance. The shifting of the rod it u wai-diy and downwardly moves the strap alo the periphery of the cylinder @fl thereby rotating the cylinder about its pivotal axis given amount. Since the pointers Si! and 82 are operatively associated with the cylinder 6H, they will be swung by corresponding amount. From the foregoing description of the new overand underweight scale it will be apparent that the invention provides a scale which is compact in size and readily adaptable to a small counter space. The new scale is characterized by an arrangement of parts which renders the weight mechanism clearly visible to the viewing public from all angles. In addition the invention provides a scale of the centrally pivoted weigh beam type which is novel, compact and which has the weight indicating mechanism and the counterpoise weights located in vertical alignment with the indicating means positioned below the counterpoise weights.
